If I may post a modest comment from an outsider who has been involved in several websites similar to this, that have all gone through similar upheavals:
If you're the one here to pick up the pieces, you're the good guy. Don't make it too complicated trying to avoid what the 'bad guy' did. (No offense, I don't mean to imply anything on this site, but I don't really know how else to phrase it.) You aren't him, you don't do things the same way in the first place, keep it simple. The best policy, it seems to me, is an iron dictatorship open to suggestions. As long as the goal is the betterment of the site and enjoyment of the members, and this is carried out faithfully and sensibly, you don't need a committee to slow things down. I suppose an oversight committee isn't the worst idea, but I'd try to only have it do anything active when there was a problem, not as a general practice. Trust me, nothing will ever be done in a timely matter by an asynchronous committee, been there, done that, and it's pretty impossible with a group of only 3. I'd bet you have enough trouble with the 2 flag officers having time to get together on minor details, they most likely trust each other enough to get things done without contacting each other unless it's a major issue.
